Abstract
Saphenous vein graft aneurysm (SVG) formation after coronary artery bypass grafting is a rare complication of the surgery. We present a case of a 68-year-old man with an unusual presentation of such an aneurysm. Thirty-four years after his initial bypass surgery, the patient presented with a fistula formation into his right atrium from a vein graft aneurysm. Late aneurysm formation is thought to occur secondary to atherosclerotic degeneration of the SVG with background hypertension and dyslipidaemia accelerating the process. Diagnostic modalities used to investigate SVG aneurysms include computed tomography, transthoracic echocardiogram, magnetic resonance imaging and cardiac catheterisation. Aneurysms with fistula formation historically require aggressive surgical intervention. Resection of the aneurysm with subsequent revascularisation if required is the surgical norm. SVG aneurysm with fistula formation into a cardiac chamber is a rare complication of coronary artery bypass grafting (CABG), which can occur with atypical presenting symptoms. Physicians should keep in mind the possibility of this occurring in post-CABG patients presenting with heart failure and a new murmur.
